Bootstrap Grid Flexbox

Plugins flexbox grid system for bootstrap 3.

Story
Behind

Before that when I developing a website with Bootstrap sometimes I get crazy
because the difference height of grid can destroying my layout, so I want to moving to use Flexbox because most
modern browser now can support Flexbox (check here) .

I choose to style the grid not to overide Bootstrap grid but just for add on to Bootstrap or as Plugins. Why?
Sometimes I still need bootstrap grid, so i chose to not replace bootstrap grid.
